Simulation of a Tele-Surgery process through a Live Video Streaming service, using Simu5G and Wowza

Telematic services that require low latency for real-time applications and that make use of wireless mobile networks are increasingly popular. In the case of Tele-Surgery services that employ Live Video Streaming (LVS), latency times of the order of 1ms are needed. Given the difficulty of implementing real 5G test scenarios that enable this type of service to be characterized, this paper presents an emulation scenario that uses Simu5G to simulate the network, Wowza as a real video server, OBS Studio for transmission and VLC media player for content playback. This emulation scenario makes it possible to modify such parameters as bitrate, bandwidth, frequency and numerology index in order to evaluate different network configurations. By varying these parameters in a controlled way, packet losses are obtained for different bitrate values. The best quality video was obtained with a bitrate of 3000 Kbps.Los servicios telemáticos que requieren baja latencia para aplicaciones en tiempo real y que utilizan las redes móviles inalámbricas son cada vez más populares. El caso del servicio de Tele-Cirugía que emplea la técnica de Live Video Streaming –LVS requiere tiempos de latencia del orden de 1ms. Ante la dificultad de implementar escenarios de prueba reales de 5G que permitan caracterizar este tipo de servicios, se presenta en este trabajo un escenario de emulación que emplea Simu5G para simular la red, Wowza como servidor real de video, OBS Studio para la transmisión y VLC media player para la reproducción del contenido. Este escenario de emulación permite modificar parámetros como bitrate, ancho de banda, frecuencia e índice de numerología; con el objetivo de evaluar diferentes configuraciones de red. Variando de forma controlada los parámetros mencionados, se obtienen las pérdidas de paquetes para diferentes valores de bitrate. De acuerdo a los resultados, y para el escenario de prueba particular, el vídeo con una mejor calidad se obtuvo con un bitrate de 3000 Kbps.

Telesurgery and Robotics: Current Status and Future Perspectives

The concept of telehealth has revolutionized the healthcare delivery system. Based on this concept, telesurgery has emerged as a promising and feasible option, providing surgical care to remotely located patients. This has become possible by advancements in the robotic system combined with the cutting-edge technology of telecommunication. Since the ability to perform telepresence surgery was hypothesized, consistent development and research in this novel area have led to the beginning of telesurgical care, which can fulfill the demand for surgical care in remote locations. In addition to the benefits of robotic-assisted minimally invasive surgery, telesurgery eliminates geographical barriers, which helps patients have better access to quality surgical care. It may reduce the overall financial burden by eliminating the travel expense of the patients, providing expertise through the telepresence of experienced surgeons, and reducing the operating room personnel. The telesurgical approach is also being utilized for telementoring, i.e., real-time guidance and technical assistance in surgical procedures by highly skilled surgeons. Despite the numerous technological improvements in telesurgery, its widespread implementation in clinical setting still lags, mandating the identification of the offending factors that limit its clinical translation

Toward a Discourse Community for Telemedicine: A Domain Analytic View of Published Scholarship

In the past 20 years, the use of telemedicine has increased, with telemedicine programs increasingly being conducted through the Internet and ISDN technologies. The purpose of this dissertation is to examine the discourse community of telemedicine. This study examined the published literature on telemedicine as it pertains to quality of care, defined as correct diagnosis and treatment (Bynum and Irwin 2011). Content analysis and bibliometrics were conducted on the scholarly discourse, and the most prominent authors and journals were documented to paint and depict the epistemological map of the discourse community of telemedicine. A taxonomy based on grounded research of scholarly literature was developed and validated against other existing taxonomies. Telemedicine has been found to increase the quality and access of health care and decrease health care costs (Heinzelmann, Williams, Lugn and Kvedar 2005 and Wootton and Craig 1999). Patients in rural areas where there is no specialist or patients who find it difficult to get to a doctor’s office benefit from telemedicine. Little research thus far has examined scholarly journals in order to aggregate and analyze the prevalent issues in the discourse community of telemedicine. The purpose of this dissertation is to empiricallydocument the prominent topics and issues in telemedicine by examining the related published scholarly discourse of telemedicine during a snapshot in time. This study contributes to the field of telemedicine by offering a comprehensive taxonomy of the leading authors and journals in telemedicine, and informs clinicians, librarians and other stakeholders, including those who may want to implement telemedicine in their institution, about issues telemedicine
